SPECIFICATION forming part of Letters Patent No. 403,203, dated May l l,18.89. Application filed February 2, 1889 Serial No. 298,472. No model.)

To all whom it may concern:

Be it known that I, JOSHUA MILLS, of Ottawa, in the county of La Salleand State of Illinois, have invented a new and useful Improvement inMetallic Shingles, of which the following is a full, clear, and exactdescription.

My invention relates to an improvementin metallic shingles, and has forits object to provide a shingle of simple, durable, and economicalconstruction, wherein the joints will be re-enforced and so formed as toeffectually check the efiects of a driving wind; and a further object ofthe invention is to provide a means of securing the shingles withoutpuncturing or otherwise perforating them, whereby the necessity ofsoldering them is dispensed with.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth pointed out in theclaims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts in all the views.

Figure 1 is a plan view illustrating three connected shingles; Fig. 2 isa transverse section taken on line 00 0c of Fig. 1. Fig. 3 is a planView of a single shingle, and Fig. 4 is a longitudinal section on line yy of Fig. 3.

In carrying out the invention the right and left longitudinal edges ofthe shingle are stamped, crimped, or otherwise manipulated to produce anoutwardly-extending triangular rib. The outer longitudinal edge of therib 10, upon the left, which is struck up from the under side, is bentinward horizontally, as shown at 11 in Fig. 2, to a point beneath and invertical alignment with the upper angle or apex of the rib. The saidhorizontal section is then bent upon itself to provide a vertical innersection, 12, as illustrated in the same figure. The rib 13, upon theright, is smaller than the rib 10, and is not projected upward as high,while the outer longitudinal edge is bent over the upper surface of theshingle, whereby a triangular rib is formed over the body. The said rib13 is provided at the inner longitudinal edge with a horizontalbasesection, 14, of less width than the equivalent section of the rib10. The center of the shingle is stamped or otherwise manipulated toproduce a central embossed figure, 15, of any approved design, and atoneend of the shingle, at 5 a the center, the surface is upwardlyembossed to form a short triangular rib, 16, extending fromthe edge,preferably, to an intersection with the lines of the figure 15, asillustrated in Figs. 1 and 3.

The edge of the shingle, at the end in which the rib 16 is produced, isbent downward and inward under the body to form a short open loop, 17,as best shown in Fig. 4. The edge of the opposite end of the shingle,between the side ribs 10 and 13, is bent upward upon itself to form abead, 18, then downward slightly from the bead in the direction of thetop of the body, and horizontally over the body in the direction of theend carrying the short loop 17. The upper fold just described producesan open loop, 19, of greater width than the opposite or under loop, 17,and the inner end of the said longer loop, 19, is strengthened by beingbent upon itself, preferably, downwardly and inwardly, as bestillustrated in Fig. 4.

In applying the shingles to the roofs of dwellings or to the sidesthereof a shingle is placed in proper position upon the roof, with, forin stance, the end carrying the narrow loop 17 downward, as illustratedin Fig. 1. One or more angled clamps, 20, are now placed in engagementwith the outer surface of the right-hand rib, 13, of the shingle, thesaid clamps be- 8 ing provided with a horizontal extension, 21, adaptedto rest upon the roof, and a nail is then driven through the extensionof the clamp, as illustrated in Fig. 1, whereby that edge of the shingleis firmly secured. The left hand rib of another shingle is then made tooverlap the right-hand rib of the shingle in position, whereupon thehorizontal section 11 of the upper rib, 10, will support the equiva lentsection, 14, of the inner rib, and the vertical section 12 of the outerrib will extend upward, essentially, in contact with the apex of theinner rib, as illustrated in Fig; 2. Thus each rib is strengthened bythe other, and the two ribs are strengthened by the vertical Ioo section12, and should force be brought to bear upon the apex of the ribs thesection 12 will tend to brace and support said sections. It will also beobserved that when the rib is made to cover or overlap the rib 13 theclamp is effectually concealed. The shingles are laid, for instance,lengthwise of the roof or of the side of the dwelling in this manneruntil as many as are desired are placed in position.

Another set of clamps, 22, is then made to engage with and hold theupper end of the shingle upon which thelong loop 19 is formed, and tothat end the clamp is provided with an inner hooked end, 23, adapted toconform to the contour of the bead 18, and an outer flange-section, 24.When the hook-section is brought in engagement with the bead 18, theflange-section 24 is in contact with the roof or side of the dwelling,and may be attached thereto by a nail, screw, or equivalent device, asbest illustrated in Fig. l. The next shingle, commencing the secondline, for instance,

' is made to break joint, and the central rib,

16, is brought in contact with the upper surface of the overlapping ribs10 and 13, and the short loop 17 is made to interlock with the long loop19. In attaching the clamps 22 to I claim as new, and desire to secureby Letters Patent, is

1. A metallic shingle provided with a triangular rib at eachlongitudinal side, the edge of one rib being carried horizontally inwardand the edge of the opposite rib horizontally inward and verticallyupward, substantially as shown and described.

2. A metallic shingle provided with a triangular rib at eachlongitudinal side, the edge of one rib being carried horizontally inwardand the, edge of the opposite rib horizontally inward and verticallyupward, and a central triangular rib located at one end of the body ofthe shingle, substantially as shown and described' 3. A metallic shingleprovided with a triangular rib at each longitudinal side, the edge ofone rib being carried horizontally inward and the edge of the oppositerib horizontally inward and vertically upward, and having a short loopat one end upon the under face and a longer loop upon the opposite endupon the outer face, and the said latter loop provided with an outerlongitudinal bead, substantially as shown and described.
